Hi @Palakgarg
Thanks for reaching out to us, and welcome to the Zoom Developer Forum.
Yes, that is possible; you can use a General Oauth app with the right scopes to call the API. Once you create your app and generate your access token, you will use it to make calls to the Zoom API and pull the data you need.
You will need to transform/save or format your data as needed in your backend and then send your data to your S3 bucket.
